Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple overload protectors (pressure switch, temperature overload protector, current overload protector) are used separately, then the air conditioning system receives comprehensive protection, but the control process becomes cumbersome and the structure becomes complicated
Solution Approach 1:
The patent combines pressure protection, temperature overload protection, and current overload protection into a single integrated overload protector. The pressure switch, temperature sensing element, and current sensing element are integrated within one device, eliminating the need for separate protectors and simplifying the overall system structure while maintaining comprehensive protection coverage.
Solution Approach 2:
The integrated overload protector performs multiple functions simultaneously: it monitors pressure through the pressure switch, detects temperature through the temperature sensing element, and senses current through the current sensing element. This multi-functional design replaces multiple specialized devices with a single universal protector that handles all protection needs.
2Reliability
If multiple overload protectors are used separately, then comprehensive protection is achieved, but the cost of the air conditioning system increases
Solution Approach 1:
By merging pressure, temperature, and current protection functions into a single integrated device, the patent reduces the total number of components required. This consolidation lowers material costs, reduces assembly complexity, and decreases manufacturing expenses while maintaining the same level of comprehensive protection.
3Reliability
If separate overload protectors are used, then each parameter (pressure, temperature, current) is protected independently, but the control process becomes cumbersome
Solution Approach 1:
The integrated overload protector combines multiple protection functions that operate independently internally but present a unified interface externally. The pressure switch, temperature sensing element, and current sensing element each monitor their respective parameters independently, yet they are controlled and monitored through a single device, simplifying the control process.
